let me expound on that....
in my advanced physics course, we proved that surface area has nothing to do with friction! the only reason dragsters use big tires is because of the extra mass they offer, and they do not wear nearly as fast. the rubber compound is also important. the only place a wide tire will help you is when you are turning. to explain this further, let me put it this way:
get a box with some weight in it. enough to be difficult to push. put the box on one of its sides and push it. now turn it to a different side and push. keep trying this -- you'll find its no easier on a smaller side versus a larger size.
as for muscle cars using wider tires in the rear, its basically a marketing gimmick. sure it helps a slight bit due to their weight, but other than that it doesn't do diddly off the line.

So...
If I could put a pair of bicycle tires on the rear of my 69 SS/RS Camaro, making sure the wheels and tires could hold up the weight of the car, my car will hook up when I romp on the throttle?

LOL... you know what they say. A little knowledge is a dangerous thing.

So Dan, let me get this straight before I waste my time typing something that might not be relevant.
You are basically saying that friction is not needed in drag racing?
Also, that the size of the tire (width wise) is also irrelevant and has nothing to do with traction? Not matter how small the tire width wise, the grip remains the same?

more like your car will flip over, too thin. Originally posted by dion:

Look here! Kid named "Dan" asked about the exact same question, and he was told to search! ROFLMAO! Isn't it ironic.... Here is another good link. Read answer one to the question (you'll have to scroll down towards the bottom)... I do believe it would apply here.

Freshman Physics wouldn't happen to be the course you both are taking, would it?

Um, essentially the physics is right, but they are missing something here, and I think a big point everyone here has missed is the air pressure in the tires.. ever notice how slicks WRINKLE(this is far more important than the thickness, width , compound rating etc...)? When a slick spins up, your contact patch is basically reduced anyways, look at a slick in slow motion in a burnout to see what i mean..)Think about all that and then ask yourself how this efects the Coeeficient of friction of the tires...(go back and think on your physics, and then pic a simple example... it might make it more clear to you...)Or better yet ask a guy running slicks to double his tire pressure and make a run for you to see what happens..
